Track Side Maintainance TRIZ Cases
- Vehicle Communication Control for Loss Detection and Safe Transition
When vehicle links fail or degrade, the controller switches paths, adapts protocols, and applies a transitional speed-reduction plan.
- Broken Rail Detection via Dynamic Current Measurement
A broken rail detection system measures track current to locate breaks without insulated joints.
- Joint Bypass Circuit for Insulated Joint Integrity Testing
Automated joint bypass circuit tests insulated joint integrity via track circuits, eliminating manual labor costs and operational disruptions.
- Train Coupler Structural Health Monitoring via Sensor Fusion
A train coupler structural health monitoring system integrates piezoelectric and ultrasonic sensors with data acquisition units for continuous condition assessment.
- Train Service Management Device Optimizing Car Count and Intervals
A service management device determines valid car counts to minimize total vehicles while maintaining required transport volume.
- SWIR Vehicle Component Imaging with Thermoelectric Cooling
Thermoelectric cooling stabilizes SWIR photoconductor arrays, eliminating emissivity errors and motion blur during high-speed vehicle monitoring.
- Vehicle Monitoring System for Dynamic Trip Plan Adjustment
A vehicle monitoring system calculates cumulative damage to generate modified trip plans that adjust operational settings like throttle and speed.
- Wayside Communication Device Dynamic Transmission Modes
A wayside communication device dynamically adjusts transmission power and reporting intervals to conserve battery energy.
- Locomotive Root Cause Determination via Keyword Similarity
Cloud platform matches historical failure keywords against current reports to replace subjective expert reviews and cut diagnosis time.
- Failsafe Rail Shunt Device with Magnetic Coupling and Self-Diagnosis
A rail-mounted shunt device magnetically couples to running rails while transmitting operational status signals to a control center.
- Relay Train Backup Communication for Broken-Down Railway Vehicles
A backup communication device establishes a wireless link with a relay train to transmit alarm data.
